Good to know I'm not the only one that has inaccurate probes. They read about 20 degrees high. Wish there was a way to calibrate the sensor, but sounds like it'll just be easier to buy a probe thermometer.
My Pitboss probes seemed reasonably accurate when checked with a Thermoworks pop. Now I use a Thermoworks Smoke probe which I am confident in. Of course it makes a difference where the probe is inserted.
All four of my PB probes are with in 5° of my ink bird probes. Takes them a little longer settle in.
It's sad that if you the APP installed on any device you have. Makes the grill go stupid on temp control.
